Latest Transmissible spongiform encephalopathies Stories

New pathway for infection reported in the American Journal of Pathology Bovine spongiform encephalopathy (BSE, or "mad cow disease") is a fatal disease in cattle that causes portions of the brain to turn sponge-like. This transmissible disease is caused by the propagation of a misfolded form of protein known as a prion, rather than by a bacterium or virus. The average time from infection to signs of illness is about 60 months. Little is known about the pathogenesis of BSE in the early...

(Ivanhoe Newswire) - 5.4 million Americans suffer from Alzheimers and 3 million from Parkinson's disease. Doctors who treat patients with these among other neurodegenerative conditions believe that the diseases are spreading though their patients' brains. The stages of both Alzheimers and Parkinson's disease show these pathological effects. Until recently, only in prion disease had this spread been shown, resulting in proof that the agent of spread is the prion protein. More recently,...

Possible Way To Prevent Brain Cell Death Discovered
2012-05-07 03:29:28

In a new study, a team of UK researchers have reportedly found a way to prevent brain cell death in mice -- a discovery which could ultimately lead to improved treatments for Alzheimer's, Parkinson's, and other neurodegenerative ailments in humans. According to BBC News Health and Science Reporter James Gallagher, scientists at the University of Leicester studied prion disease, which affects mice in much the same way as Alzheimer's, Parkinson's, Huntington's and Creutzfeld-Jacob Disease...

USDA On The Hunt For Offspring Of BSE-infected Cow
2012-04-26 13:30:59

Lawrence LeBlond for RedOrbit.com After tests this week confirmed BSE (bovine spongiform encephalopathy) in a dead dairy cow from a California farm, the US Department of Agriculture (USDA) went on the manhunt, or cowhunt, for any offspring the dead animal may have had, stating they could also carry the fatal brain-eating disease. But while USDA officials say there is evidence that the disease can be passed on from a mother to their calf, John Clifford, the agency´s chief...

California Mad Cow Case Poses No Threat To Humans

Lawrence LeBlond for RedOrbit.com The first case of “mad cow” disease in six years has cropped up on a California dairy farm after health and food experts discovered the disease in a dead cow, the US Department of Agriculture (USDA) confirmed on Tuesday. Officials are calling the discovery a stroke of luck because tests are performed on only a small percentage of dead animals that are sent to the transfer facility in Hansford, California. “We randomly pick a number...

Toxic prions in the brain can be detected with self-illuminating polymers. The originators, at Linköping University in Sweden, has now shown that the same molecules can also render the prions harmless, and potentially cure fatal nerve-destroying illnesses. Linköping researchers and their colleagues at the University Hospital in Zürich tested the luminescent conjugated polymers, or LCPs, on tissue sections from the brains of mice that had been...

Prion proteins may be best known for their role in infectious diseases, but not all of them are destructive, new research shows One of the greatest mysterious in cellular biology has been given a new twist thanks to findings reported in Science. Researchers at the RIKEN Brain Science Institute show that prions, proteins that transmit heritable information without DNA or RNA, can contribute to drug resistance and cellular adaptation. Their discovery of a yeast prion with these properties...

Computer modeling supports theory that many dementias spread like prion diseases A new technique for analyzing brain images offers the possibility of using magnetic resonance imaging (MRI) to predict the rate of progression and physical path of many degenerative brain diseases, report scientists at the San Francisco VA Medical Center and the University of California, San Francisco. The technique, developed by SFVAMC scientists in collaboration with a team led by Bruce Miller, MD,...

Weill Cornell scientists say the program might help patients manage their disease Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of...
